Check Digit Verification of cas no

The CAS Registry Mumber 22319-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22319-71:
(7*2)+(6*2)+(5*3)+(4*1)+(3*9)+(2*7)+(1*1)=87
87 % 10 = 7
So 22319-71-7 is a valid CAS Registry Number.

A highly selective method for the synthesis of 1,3-diarylbenzo[f]quinoline derivatives catalyzed by silver triflate

Wang, Xiang-Shan,Zhou, Jie,Zhang, Mei-Mei,Wang, Wei,Li, Yu-Ling

experimental part, p. 935 - 938 (2012/07/16)

The three-component reactions of aromatic aldehydes, naphthalen-2-amine, and phenylacetylene catalyzed by AgOTf in toluene selectively gave 1,3-diarylbenzo[f]quinolines in high yields. This procedure provides an efficient method for the synthesis of benzo[f]quinolines under mild reaction conditions and with high yields, high selectivity, and operational simplicity.
